21. Cadillac Eldorado 1976
The 1976 Eldorado was an automotive dinosaur in many ways. It was the last Cadillac they produced with the enormous 500 CID V8 engine, one of the biggest car engines GM ever made. It was the last Cadillac convertible for over 10 years since the late 1970s when restrictive safety laws almost killed the convertible class. Also, it was the last of the truly big land yacht that dominated the domestic car industry in the 1970s.
During the production of this generation of the Eldorado, it was obvious the industry was changing. Cadillac had to rethink their strategy to stay on top of the game. However, the glorious 1976 Eldorado was the perfect way to end an era of monstrous engines, soft rides, and plush interiors.
